MACHINE FOR HOLDING GLASS CYLINDERS WHILE BEING C' UT.

SPECIFICATION forming part of Letters Patent No. 627,288, dated June 20,1899.

I Application filed March 1, 1899. Serial No. 707,349. (No model.)-

To (0Z7, whom it may concern:

Be it known that I, CHARLES E. BALL, a citizen of the United States,residing at Alexandria, in the county of Madison and State of Indiana,have invented new and useful Improvements in Machines for Holding GlassCylinders while being Cut, of which the following is a specification.

My invention relates to machines for holding'and rotating glasscylinders while being cut to remove the jagged or roughened ends; auditsobject is to provide an improved construction of the same for securelyholding a glass cylinder-such, for instance, as a lam pchimney-withoutliability of breaking the same.

The invention consists in the novel construction and combination ofparts hereinafter fully described and claimed.

In the accompanying drawings, Figure 1 is a longitudinal sectional viewof a machine constructed according to my invention for holding androtating a glass cylinder. Fig. 2 is a side elevation of the same. Fig.3 is a plan View. Fig. 4 is an end elevation.

In the said drawings the reference-numeral l designates the base of themachine, upon which are mounted two parallel standards 2, formed intheir upper edges with semicircular recesses 13, and seated upon thesestandards are corresponding standards 4, having semicircular recesses 5in their lower edges. The standards 4 are connected together at theirupper ends by aplate 6, and when placed on the standards 2 there are twoopposite circular holes formed by the said recesses in the edges, whichserve as bearings for a rotatable cylinder 7. This cylinder, which is ofmetal, wood,or othersuitable materiahis formed with peripheral grooves8, which engage with the edges of said holes. A driving-belt 9 passesaround the cylinder between the grooves for rotating it. Inserted in oneend of said cylinder is one or more removable rings 10, of cork or othersuitable yielding or elastic material, for receiving the base or lowerend of a lamp-chimney or other object and are made removable and ofdifferent sizes, so as to accommodate them to chimneys of varyingdiameters. I-Iooks 11 are connected with the cylinders 7 for holdingsaid rings in place.

At the opposite end of said cylinder are two semicircular segments 12,also of cork or other elastic material. These segments do not fit insaid cylinder like the rings 10, but abut against the same and are heldin. place by a hinged gate 13, consisting of two semicircular metallicstraps l4 and 14:, passing around the cylinder and projecting beyond theend of the same. These straps at their lower ends are hinged or pivotedto rods 15, secured to the cylinder, and pass up around the segments.Said rods are connected together by plates 16. At the upper ends saidstraps are cut away at 17and are formed with slots 18, through whichproject pins 19, secured to the cylinder, which assist in holding thestraps on the cylinder. Secured to one of said straps near the upper endis a log 20, to which is pivoted a lever 21, one end of which is curvedinwardly, forming a cam 23, and the extremity bent into a hook 2st.Engaging with this hook is an arm 23, secured to the other strap 14. Thenumeral 26 designates a catch secured to said cylinder, having its freeend bent downwardly, forming a hook with which said lever engages whenthe straps are closed to lock the same.

. The operation is as follows: The straps are openedbydisengagingtheleverfromitscatch, allowing the segments to spread apartslightly. A lamp-chimney is now inserted in the cylinder by passing theupper end thereof through the ring 10 and out between thesegments. Bothends of the chimney will new project a short distance beyond thering'and segments. The straps are now closed by means of the lever 21clamping the upper end of the chimney firmly between the segments andthe cylinder rigidly rotated by the driving-belt. The chimney will becorrespondingly rotated, and wires are then pressed against thesameatthe points desired to be out, which by their trictional contactwill heat the glass very hot at such points. If the chimney be nowtouched by a piece of cold steel or water be dropped thereon at suchheated points, the chimney will break thereat, leaving the ends of thelatter smooth and'sharp. These sharp edges can be subsequently rounded,if desired, in the manner well known to those skilled in the art. Thesaid segments may be of varying sizes and removable, so as toaccommodate lamps of varying diameters, and owing to their yielding orelastic nature they will securely hold the chimney, yet not injure thesame.

Having thus fully described my invention, what I claim is- 1'. In amachine of the character described, the combination with the rotatablecylinder, of the ring of elastic material 'removably inserted in one endthereof, the hooks for holding it in place, the elastic segments at theop-' posite end of and abutting against said cylinder, the hingedsemicircular straps surrounding said segments and means for looking thesame, substantially as described.

2. In a machine of the character described, ihe combination with thebase, the standards formed with semicircular recesses, the rotatablecylinder formed With peripheral grooves engaging with said standards,the elastic ring removably inserted in one end of said cylinder and thehooks connected With said cylinderfor holding said ring in place, of theclastie segments abutting against the opposite end of said cylinder, thesemicircular straps surrounding said segments formed with slots, theplate, the pins passing through said slots, the plates to which saidstraps are hinged and means substantially as described for locking saidstraps.

3. In a machine of the character described, the combination with therotatable cylinder, provided with pins near one end and the rods.secured to said cylinder, of the semicircular CHARLES E. BALL.
